No. 557,921 4Claims. (Cl. 229-55) This invention relates to bag constructions, andmore specifically concerns bags which may be formed of transparent,flexible materials.

An object of this invention is to provide improved bag constructionshaving stidening inserts for imparting shape to the bag or forsupporting the contents thereof, such inserts additionally providingmeans extending externally of the bag for suspending the bag from asupport.

Another object of this invention is to provide an improved bagconstruction having a stifening insert within the bag and including aportion projecting through an opening in the bag to provide means forsuspending the bag from a support or for handling the bag, and furtherincluding a portion for shaping the bag in its third dimension.

A further object of this invention is to provide an improved bagconstruction and a stiering insert therefor; the insert having a portionprojecting through an opening in the bag, the bag and insert havinginterengageable portions for retaining the bag and insert in engagedrelation, yet allowing the insert to be removed from the bag.

Still another object of this invention is to provide an improved bagconstruction having a self-sealing liap construction; such apconstruction lending itself to operative relationship to Stileninginserts which may be dis posed within the bag.

Other objects of this invention will in part be obvious and in parthereinafter pointed out.

FlG. 7 is a transverse sectional view similar to that of FiG. 6 andshowing a modified form of stilening insert. v

Referring in detail to the drawing, and particularly to FIGS. 1-3, 10designates a bag construction embodying the invention. The samecomprises rectangular shaped front and back walls 11, 12 of flexiblesheet material such as polyethylene, cellophane, or the like., which aresecured together at their side edges 13. The walls 11, 12 are furthersecured adjacent their top edges, as at 14, 15, along lines extendinginwardly from side edges 13; the inner ends of said linesterminating atopposed, spaced points i6, 17, to leave an opening 18 defined by theunsecured wall portions between points 16, 17.

The bag walls 1,1, 12 are preferably formed of limp transparentmaterial, and which does not readily maintain its own shape. The bag 1i)may be used for packaging a variety of merchantable items which may beviewed by the purchaser while still within the bag.

Means is provided for imparting shape to the bag for supporting thecontents thereof; for carrying indicia thereon visible through the wallsof the bag; and for suspending the bag and its contents from a suitablesupport so as to present the same for inspection by customers.

Accordingly, a at insert sheet 19 of stiff material such as cardboard orthe like, is inserted within the interior of bag 1li. Such insert 19 isof an outline similar to that of the bag, with the sheet edges adjacentthe edges of the bag. The insert 19 includes a tongue portion 20extending from a central portion of top edge 21 thereof, said tongueportion 26 projecting through opening 18 in bag 16. An opening 22 intongue 2G allows the same to receive a rod, not shown, or other suitablesupporting means, whereby the bag 10 and its contents are suspendedtherefrom. v Y

The contents of bag 1t), not shown, may be mounted on insert 19,concealing the same, except for tongue Ztl, as for example a shirt orthe like; Alternatively, the bag contents may be suitably mounted on oneside of insert 19. In either case, insert 19 will maintain the shape ofthe bag contents and also shape the bag 10.

The insert 19 together with the bag contents are introduced into bag 1i?through the bottom, open edges thereof, the tongue Ztl projectingthrough opening 18, and the bottom wall edges may then be suitablysealed together as at 23; or if desired, such bottom edges may be leftopen.

It will be apparent that the shouldered edge portions 2i of the insert19, or the bag contents overlying such edge portions, will abut the seallines i4, 15' of bag 10 to retain said insert and b-ag contents withinthe bag. The tongue portion 2li of the insert 19 provides means forhandling the bag 19, as well as suspending the saine in a verticalposition from a suitable support.

As shown in FIG. 4, the insert 19 may be of extended length and providedwith parallel fold lines 24, 25 adjacent the lower end thereof, to forma narrow, thickness ilap 26 and an end ilap 27. Such ilaps 26, 27 areadapted to be located adjacent the bottom edge of bag lil, with flap 26imparting a given thickness to the bag. The ap 26 may be imprinted asdesired to give information as to sizes and the like, in which case,bags lilmay be disposed flatwise on shelves with the bottom edgesthereof exposed to view. Other portions of insert 19 may also beimprinted as desired, the indicia so imprinted being visible throuf'hthe transparent walls 11, or 12..

The invention herein may be further embodied in the form shown in FIGS.5, 6. Thus, bag 3d has a front wall 31, a back wall 32. sealed theretoat the side edges 33 and bottom edges 33a. The top edge 34 of back wall32 projects above the top edge 35 of front wall 31. A ap 36 extends fromedge 34 of wall 32, being folded downwardly towards the front face ofwall 32, the free edge 37 of said ap being located below the edge 3-5 offront wall 31. The opposite ends of flap 36 are sealed between the sideedges 33 of the walls 31, 32, thus forming a pocket between said ap andback wall 32.

The bag 36 may be used in conjunction with a at stiiening insert 3S ofcardboard or the like. Such insert is formed with a tongue 39 extendingupwardly from a central portion of top edge 40 of the insert. Recesses41 are formed on either side of tongue 39, providing laterally disposedprojections 42. The insert 3S may be of an outline similar to that ofbag 30 and is adapted to be associated with the contents of the bag, notshown, in a manner previously described.

The insert 33, together with the bag contents mounted thereon, isdisposed within bag 30 by inserting the same through the opening betweenwall 31 and flap 36. The insert 38 is moved downwardly so that bottomedge 43 thereof approaches bottom edge 33a of the bag and bringing thetop edge 40 of the insert below the edge 37 of flap 36. The insert 38 isthen moved upwardly while deilecting projections 42 inwardly to receivethe same between ap 36 and back wall 3,2. Tongue 39 will project aboveedge 34 of the bag to provide means for handling the bag and to suspendthe same, in the manner previously described.

As shown in FIG. 7, bag 30, similar to that shown in FIGS. 5, 6, isprovided with a at, stiffening insert 45 of cardboard or the like, andsimilar to insert 19 shown in FIG. 4, except that ap 27a, correspondingto flap 27, is extended so that the upper edge 46 thereof is receivablein the pocket formed between ap 36 and back wall 32 of bag 30, to retainthe insert within said bag.

Bag 30 may be used without inserts 38 or 45, the same Ibeing selfsealing in use. Thus, the bag contents, not

. shown, in flat sheetlike form, may be inserted through the openingbetween ap 36 and front wall 31, moved downwardly toward bottom edge33a,rand the upper portion of the sheetlike contents is tucked into thepocket formed by vap 36 and back wall 32. Such bag contents will thenpress the ap 36 outwardly into contact with front wall 31 to form aneffective seal for the bag, the seal being enhanced by stretching theside edges 33 of the bag 30 at the upper portions thereof, away Vfromeach other.

It is understood that the dimensions of the inserts v 38, 45 are such asto allow for successive downward and upward movement lwithin bags 30,taking into account the bag contents associated therewith, so as toproperly engage the inserts with the retaining portions of the bag.

As various changes might be made in the embodiments of the inventionherein shown, without departing from the spirit thereof, it isunderstood that all matter shown or described shall be deemedillustrative and not by way of limitation except as set forth in theappended claims.
